Label printing using microporous label surface

Abstract

Labels are printed from a liquid ink having mineral oil by printing on a sheet having a Teslin brand synthetic paper lamination followed by an organic adhesive lamination in contact with the synthetic paper, followed by a supporting lamination. The synthetic paper can be as thin as 8 ml and no barrier layer is needed to protect the adhesive from the mineral oil.

What is claimed is: 
     
       1. The method of preparing labels having an organic adhesive backing degradable by mineral oil for affixing said labels to surfaces comprising printing on a print-receiving lamination with imaging ink or toner containing mineral oil as a vehicle, said print-receiving lamination being in contact with a lamination of said adhesive, and said adhesive being contacted by a supporting lamination, said print-receiving lamination being of a porous material which holds said mineral oil of said ink or toner in the pores of said porous material away from said adhesive. 
     
     
       2. The method as in claim 1 in which said material of said print-receiving lamination is a porous polyolefin base having a major amount of siliceous filler. 
     
     
       3. The method as in claim 2 in which said material of said print-receiving lamination is microporous plastic sheet. 
     
     
       4. The method as in claim 3 in which said material of said print-receiving lamination is in the order of magnitude of 0.008 of an inch thick.
